Was working fine for over a year, now won't boot. LEDs on the GFX card and one on the MOBO labeled PWR glow when plugged in, but nothing happens when I push power and shorting switch pins does nothing either. If I pop out the CMOS battery and put it back in then try the fans lurch but nothing happens. Shorting the 15 and 16 pins turns the PSU on, and when the 24pin connector is attached to the MOBO it will start up briefly then stop. If I plug in the CPU header it returns to what I described, no power but will lurch after replacing the CMOS battery. Should I be shopping for a new PSU or is there another problem maybe?

12.04 upgrade broke grub? (not wubi related)

as seen on Ask Ubuntu - Search for 'Ask Ubuntu'
I just updated from 11.10 to 12.04, with no major problems (it took a while to get past a request to restart ssh, mysql and some other services, but I did no fiddling by myself, everything was done by the installer). However, after restarting, grub can't do anything. Picking the new linux installation… >>> More
